Wan-Bissaka has enjoyed a breakthrough season for the Eagles, missing just three Premier League games and enhancing his reputation to the point where a number of the division's biggest teams have been credited with an interest in the 21-year-old.

United are understood to be one of the most interested parties and view the right-back as a long-term replacement for captain Antonio Valencia, who will leave the club this summer.

Metro reports that the Red Devils have now earmarked Van Aanholt as a possible target to bolster their full-back options on the opposite flank too.

Ole Gunnar Solskjaer has reportedly been particularly impressed by the 28-year-old's attacking attributes and believes that he can provide extra competition for Luke Shaw.

United are hopeful that £50m will be enough to prise both players away from Selhurst Park, although Palace are reluctant to lose either of them with Wilfried Zaha also expected to leave the club this summer.
